Thanks Bruce, I will post a picture of the blade but it is in a sad state. Unsigned and extremely shortened but definitely an old koto blade. The wood liner in the saya did some damage to the blade (moisture) and the wood is very fragile. Unfortunately it will probably stay this way. Not sure this would warrant a polish.
The second hanger is solid not removable. One of the interesting points is that the handle seems to be made in relation to the blade length (23 in). The handle is at least 2-3 inches shorter than other type 19s I have seen with longer blades.
Thanks,
Eric
